It sounds like your trailer has Bearing Buddies installed in place of grease caps. The zerk fitting where you insert the grease is sitting on a spring loaded disc or piston that will move outward away from the hub as grease is added. Push on the edge of the piston with your finger. If the disc doesn't move, add grease until the piston moves. You don't want to overfill the hub, as it will cause the grease seal at the rear of the hub to blow out and let the grease escape.

I've linked you to an install video you might find helpful.
